How to show a description on a Facebook opengraph story styled as a map

Question

In my app its possible to report accidents. When doing this, the user can post this to Facebook. I would like to show the accident on a map together with the address.

Because an accident only has a location and an address, I can't give it a title. But because there is no title, nothing is shown in the box above the map marker.

Also Facebook does not make it possible to to add text above or below the map if you want to show the story as a map instead of an item.

So where can I put the address? Currently I put it in the description but the description is nowhere visible...

Am I missing something here?

It's late, but my answer might help other people.

Your JSON should contain the "og:title" like below

{ "og:url": "http://samples.ogp.me/887352634705379", "og:title": "Sample Itinerary", "og:type": "namespace:object_type", "og:image": "https://fbstatic-a.akamaihd.net/images/devsite/attachment_blank.png", "og:description": "", "fb:app_id": [fb-id] }

Now "Sample Itinerary" will be displayed as the name of the pin.
